if someone is willing to ship to you, it'll usually work fine, the USPO knows how to handle things - more important is once you find some, get the setup ready before you order - worms settle in best if there's some microbially rich, actively decomposing material they can dive into, if there's not much interesting they'll wander or die off .... try a request on the nearest Freecycle to you, or any free ad paper serving your town, there'll be a gardener around who'll supply you with some for free or cheap

Heidi,
If you don't have any luck on freecycle or Craig's list let me know and I will sell you some. I ship all over the states and all the worms have made it through transit in fine shape, even during the last heat wave.
